If continuity and voltage is not as specified, replace the master switch.







Passenger's and rear switch: INSPECT PASSENGER'S AND REAR POWER WINDOW SWITCH CONTINUITY
If continuity is not as specified, replace the switch.

Window up: INSPECT FRONT WINDOW JAM PROTECTION LIMIT SWITCH OPERATION




a. Disconnect the connector from the master switch.
b. Connect the positive (+) lead from the ohmmeter to terminal 17 and the negative (-) lead to terminal 2.
c. Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 9.
d. Check that the continuity exists when the window goes up.




e. Check that the no continuity exists when the window is in the fully closed position.
If operation is not as specified, replace the motor.

Window down: INSPECT FRONT WINDOW JAM PROTECTION LIMIT SWITCH OPERATION




a. Connect the positive (+) lead from the ohmmeter to terminal 17 and the negative (-) lead to terminal 2.
b. Connect the positive (+) lead from the battery to terminal 9 and the negative (-) lead to terminal 4.
c. Check that the continuity exists when the window goes up.




d. Check that the no continuity exists when the window is in the fully opened position.

NOTE: If connecting the wire harness wrongly, the sensor might be damaged so caution is necessary.

INSPECT FRONT WINDOW JAM PROTECTION PULSE SWITCH OPERATION




a. Connect the positive (+) lead from the electrical tester to terminal 14 and the negative (-) lead to terminal 2.
b. Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 9.
c. Check that pulse is generated during the motor running.




d. Reverse the polarity and check that the pulse is generated.
If operation is not as specified, replace the motor.

NOTE: If connecting the wire harness wrongly, the sensor might be damaged so caution is necessary.
